TEMPERATURE-DEPENDENCE OF LOW-ANGLE STRUCTURE FACTORS OF LIQUID ALKALI-METALS USING ELECTRON-ION PLASMA MODEL

The analytic solution of EIP model in the MSA via the OCP criterion yi elds temperature dependent results in RPA quite satisfactorily at high temperatures. The same set of parameters produces low and high angle structural properties. The model can work almost near to the critical point if the ion-core radius is allowed to vary systematically in the region rho < 2rho(c), rho(c) being the critical density. The model can also accommodate the general scaling behaviour observed for the struc ture factors of liquid alkali metals.
